Abstract

Ensemble (20) conçu pour être utilisé dans un système de suspension de véhicule et accouplé à une roue (14) de ce véhicule. Cet ensemble comporte une première et une deuxième parties creuses repoussées à la presse (42, 44). Dans un mode de réalisation de cet ensemble (20), des montages pivotants supérieur et inférieur (110, 68) sont accouplés aux parties creuses repoussées (42, 44). Une partie montage de roue (24) est accouplée pivotante aux montages pivotants supérieur et inférieur (110, 68). Ces montages pivotants (110, 68) permettent de tourner la roue orientable (14) du véhicule afin de commander ce véhicule (10). On peut mettre en application cet ensemble (20) en association avec une roue (16) non orientable. Dans ce dernier cas, il est possible d'éliminer la partie montage pivotante (24) de roue.
